' .5a are TIME-INDICATOR.

To all whom it may concern:

Be it known that I, CHARLES S. CoMiNs, a citizen of the United States,and a resident of VVollaston, in the county of Norfolk and Commonwealthof Massachusetts, have invented certain new and useful Improvements inTimel[ndicators, of which the following is a specification.

One of the annoying details of shop practice is the task of keepingaccount of the time expended by the men upon job work. In the firstplace, the time is usually in hours and fractions, and the cost-chargeis in decimal parts of a dollar, rendering the calculations very liableto error, as well as slow and bothersome. Further, several fractionalperiods of time must frequently be added together in making up the totalexpense account of a single ob, thus still more increasing theawkwardness and unreliability to the total. Moreover, the attempt tofigure out the exact time between a certain hour and fraction in themorning and another in the afternoon, and especially to deduct thenoon-hour, is even more annoying and provocative of mistakes.

The object of this invention is the construction of a time-recordingdevice which shall reduce to a minimum all these troubles.

Referring to the drawings forming part of this specification, Figure 1is a front elevation of a time recorder made in accordance with myinvention. Fig. 2 is a central vertical section of a part thereof. Fig.3 is a face view of a part of the radial pins designed for carrying thetime-designating plates. Fig. 1 is a detail View showing the support forthe said plates. Fig. 5 is a perspective view on an enlarged scale ofone of the adjustable devices for holding said support.

This time recorder is equipped with any suitable clock-work communcatingits motion in the usual manner through a spindle 1 to the minute hand 2(Fig. 2), and by reducing gears 3, 4 to the sleeve 5 and hour hand 6.Behind these hands is a customary dial 7; the purpose of said dial andhands being a corrective one, to insure the user that the less evidenttime recording devices to be hereinafter described, are correct and thatthe clock-work has not run down. Directly behind the-dial and fastenedupon said sleeve 5 is a disk 10 bearing a large number of radial pins 11each pivotally car- Specification of Letters Patent.

rying a time-plate 12. The number of these plates is preferably aboutten times the hours of a working day, in order that each hour shall bedivided into decimal parts. Said pins are held by said disk by formingthe latter with a bead 13 (Fig. 2) through which radial holes aredrilled, and into which holes the pins are introduced and fastened inplace by bending up the inner ends of the pins. The outer ends of thepins being formed with heads 14, each pin is first passed through an eye15 of its associated plate 12 before its insertion through said bead.This method of pivoting the time plates is both economical and exact, aswell as durable. Said disk being mounted upon the sleeve 5 andadjustably held thereby, as by a set screw 16, it makes a completerotation in twelve hours.

Exterior to the upper quantity of time plates and keeping the same fromswinging downward, as shown in Figs. 1 and 4t, is a rail 17. As the disk10 slowly revolves, said plates one after the other reach the extremityof said rail and drop to a nearly vertical position, as indicated inFig. 1. Upon the faces of the plates thus exposed are the indi catornumerals, while the opposite faces are blank. Inasmuch as the fallenplates overlap each other far enough to cover all the numerals save theone or ones on the plate last dropped, there will remain exposed for atenth of an hour each of said indicator plates in succession, and byhaving the same in numerical order beginning with the hour of commencingwork in the morning, a glance thereat at any moment during the day willreveal the number of hours and decimal parts thereof which have elapsedsince such commencement of work. Inasmuch, however, as it is customaryto take out an hour or a half-hour for noon-time, I do not number theindicator-plates belonging thereto, but begin again at the close of thenooning the numbering which terminated at the moment of stopping work.For example, if the days work begins at 7.30 and the nooning at 12.30,five hours will have elapsed and the last time-indicator numeral willshow as 50. Then, if the noonrecess be thirty minutes, theindicator-numeral which will drop into viewat one oclock will be 50again (since the former 50 was exposed but a second during workingtime),and in a tenth on an hour past one,

the numeral 51 will be seen, and so on. If, i

now, the job which was begun at 7.30 lasted until two-twenty-four, thenumeral which will then be noted by the workman will be (Set, asillustrated in Fig. 1, since from one to 2.21 is 1.5L hours. The of themornings time added to this H of the P. M. amounts to the 64;illustrated. It the workmans pay, or, rather, the shops charge for theworkmans time, is at the rate of fifty cents an hour, a. tenth of anhour is five cents. The (5-1: multiplied by live cents gives $3.20 asthe total to be charged for the job.

To enable the same lot of clocks to suit ditferent concerns, some ofwhich begin at seven and others at 7.30, the disk 10 can be shifted topresent the zero indi-ator-plate at the time desired, such adjustmentbeing permitted by the set screw 16 which holds said disk in place uponthe spindle 1.

To permit the rail to be angularly adjusted, so that theindicator-plates will drop into view at the exact proper moment tocorrespond with the clock-hands on the dial, the rail 17 is adjustablysupported by means of the collars 19 held by set screws 20. As shown inFigs. 1 and each of said collars is formed to inclose or clasp both therail 17 and a bar 21 projecting radially inward from the posts 22, saidbars passing through the slots 23, while said rail lies between saidbars and the overhanging flanges 2t, as shown 1n Figs. 2 and 5. Byunloosening the set screws 20, the rail 17 can be slid concentricallywith the spindle 5 as much as needed.

As set forth in Fig. 2, the bars 21. are formed with elbows 25 attachedto the dial 7 and suitably supporting the same.

lVhat I claim as my invention and for which I desire Letters Patent isas follows, to wit;-

1. The combination with a clockwork mechanism, of a circular memberrotated thereby, pins projecting from and carried by said member, saidpins being in substan tially the same plane as said member andprojecting radially therefrom, and indicator plates swinging on saidpins.

2. The combination with a. clockwork mechanism, a dial, and hour andminute hands moved by said mechanism over said dial, of a circular platelocated behind said dial and rotating with said hour hand, pinsprojecting radially from the periphery ot said plate, and indicatorplates swinging on said pins, each plate bearing a number designatingthe number of predetermined timeiutervals occurring between a certaintime in the early part of the day and the moment when such plate comesinto sight.

3. The combination with a clockwork mechanism, of a circular diskrotated thereby having a half-round bead about the periphery thereof,said bead having radial holes iormed through its walls, headed pinslocated in said holes and held therein by being bent, and indicatorplates having eyes fitted upon said pins.

The combination with a clockwork mechanism, of a member carried therebyhaving a multiplicity of indicator-plates swinging on radial axes, and arail adjustably supported ii'or holding from dropping all but thedesired 'indicator-plate.

T he combination with a. clockwork mechanism, of a disk rotated therebyonce in twelve hours, radial pins projecting from said disk,time-indicator plates pivotally carried by said pins, a curved railsupported in front of the said plates which are uppermost andcontrolling the dropping of the .anie, and a clock dial located withinand concentric with, said circle of plates, said mechanism beingprovided with and properly actuating hands carried in front of saiddial.

In testimony that I claim the foregoing invention, I have hereunto setmy hand this 17th day of October, 1910.
